About

Open source ambient lighting implementation for television sets based on the video and audio streams analysis, using performance improvements especially for USB grabbers. Single and multi-threaded video processing optimization for Windows, macOS and Linux x64 & ARM (Raspberry Pi and others) for SDR/HDR streams captured by USB grabbers using pre-calculated LUT tables. Direct support for USB grabbers under Windows 10 (Microsoft Media Foundation), Linux (v4l2) and macOS (AVFoundation). Also software screen grabbers are available now πŸ†•

v17

Download packages & sources

Official releases:
https://github.com/awawa-dev/HyperHDR/releases

Installers of the latest testing version (artifacts available in the latest build):
https://github.com/awawa-dev/HyperHDR/actions

Default LUT table is already included (in the installers) but you can generate your own or import 3dl Autodesk lut table.
For Raspberry Pi you may use prepared SD card images: manual
Default hostname for SD images is HyperHDR so connect to http://hyperhdr:8090/
SSH and SPI are enabled on default.

FAQ:

You don't need to use an HDR source to use HyperHDR. You can just benefit from: high performance & optimized video proccessing, capability of using multithreading to avoid bottleneck resources, support for modern USB grabbers under Windows 10/Linux/macOS, decicated fast USB LED drivers (HyperSerialEsp8266, HyperSerialESP32 and HyperSerialWLED) or SPI driver (HyperSPI), screen grabbers including DirectX11 with HDR tone mapping, easy to use JSON API (both POST and GET), easy to setup automatic video signal detection, music capabilities and anti-flickering filter for best movie experience.

Use linux 'top' command with per core view (press 1) or preferable 'htop'. On Rpi 2/3/4 max limit is 400% (4 cores per 100%). The problem will occure when one of the core's usage is close to the 100% limit, not when overall usage is for example between 200-300% where each core if far from the individual limit.

Check the performance statistics that are updated every minute in Systemβž”Log page.

Use preferable YUV(YUY2) or XRGB(RGB32) encoding formats if it's possible. They provide better quality and lower CPU usage.

Thanks to our colleague @mjoshd there is a HyperHDR integration plugin for Home Assistant. Check the details on the website of the project https://awesomeopensource.com/project/mjoshd/hyperhdr-ha πŸš€ πŸ†•

We do not support driving WS281x and especially SK6812 LED strips directly from the Raspberry Pi although it's theoretically possible: link. If you made it and it works, fine, but most of our users weren't so lucky. You should use external ESP8266/ESP32 (preferable with CH340G or CP2104 onboard) and the voltage level shifter. ⚠️

Usage of WS281x LED strip with Rpi directly (PWM mode) requires root privilages. Otherwise you may get 'Error message: mmap() failed' (read more) ⚠️

It's possible to switch off/on HDR tone mapping remotely with home automation system. You can build commands for HyperHDR using our JSON API playground πŸ†•

Before and after HyperHDR LUT correction on HDR/BT2020 video that was broken by the USB grabber.
Without it your ambient lighting colors will be washed-out:
